ATTORNEYS 5 3,044,207 ARTIFICIAL FISHING LURE Edgar A. Dorsett, 150 Hill St., Santa Monica, Calif. Confirmation of application Ser. No. 677,929, Aug. 13, 1957. This application Dec. 8, 1959, Ser. No. 858,192 4 Claims. (Cl. 43-4231) This invention relatesgenerally to fishing lures and more particularly to an improved artificial lure for casting in which the action of the lure in the water may be controlled by the fisherman through the medium of the fishing line. This application is a continuation of my application Serial No. 677,929 filed August 13, 1957, now abandoned.

A primary object of this invention is to provide a lure designed to float on water regardless of the angle or position at which the lure first enters the water on casting and yet by control through the fishing line the lure may be made to sink at the will of the fisherman.

Another important object is to provide a controllable fishing lure meeting the foregoing object so designed as to enable movements to be executed for the purpose of both attracting fish and controlling the level at which the lure will float.

Still another object is to provide a fishing lure incor: porating noise generating means also performing the function of augmenting pitching movements of the lure started by the fisherman to the end that improved action can be realized.

Briefly these and other objects and advantages of this invention are attained by providing an elongated body having a hollow interior preferably divided into a single upper air tight chamber and relatively larger front and rear chambers. The rear chamber includes a plurality of openings to the exterior of the body so that when the lure is cast into the water, it will fill with water and cause the lure to float with its front end at a higher level than its rear end. The front chamber on the other hand includes only a single opening positoined in the bottom wall portion thereof. The air tight upper chamber serves to stabilize the lure against roll about its longitudinal axis so that it will assume an upright position. Suitable fish hooks are arranged to be secured to the bottom of the body and a fishing line may be secured to the front end.

With the foregoing arrangement, successive pulls on the fishing line after the lure has been cast into the water will result in a relative flow of water along the bottom of the lure. Because of the strategic positioning of the single bottom opening to the front chamber, a reduced pressure area as a consequence of such flow is established adjacent the opening thereby drawing out some of the air in the front chamber. When the tension on the line is reduced, the front chamber will only ship a finite quantity of water to replace the'removed air. In addition, the lure can be caused to pitch enabling additional water to be shipped when the front chamber is lower than the rear chamber. Thus, by successively varying the pulling of the line, the fisherman can gradually increase in steps the quantity of water in the front chamber until such time that the front chamber is filled. The lure is designed to 60 sink when both the front and rear chambers are filled but the air tight upper buoyant chamber will still maintain the lure in its upright position so that continued control 2 of the same may be had by the fishing line even though the lureis under Water.

An elongated tube with a weight movable therein may also be incorporated in the interior so that the pitching action will be augmented. In addition, a diving vane may be incorporated on the front end of the body to facilitate initial pitching-movements upon pulling of the fishing line.

A better understanding of the inventoin will be had by referring to a preferred embodiment thereof as illustrated in the accompanying drawings in which:

FIGURE 1 is a perspective view of the improved fishing lure of this invention;

FIGURE 2 is a cross section taken in the direction of the arrows 2--2 of FIGURE 1 showing the lure in the position it will assume when floating on the water after casting; and

FIGURE 3 is another cross section similar to FIG- URE 2 but showing the relative position of the lure with respect to the water in response to controlled forces transmitted through the fishing line by the fisherman.

Referring first to FIGURE 1, the fishing lure comprises an elongated body 10 including rear openings 11, a front diving vane 12, and suitable means at the front end for securing a fishing line 13 as shown. Fish hooks 14 and 15 are secured to the underside of the lure as shown.

Referring now to FIGURE 2, it will be noted that the interior of the body 10 is hollow and includes wall means including a Wall section 16 and wall portions 17 and 18 at the upper interior of the body. The wallsection 16 runs transversely of the longitudinal axis of the body and divides the interior into a front chamber A and a rear chamber B. The upper wall portions 17 and 18 in turn define an upper air tight chamber C. The various openings 11 communicate only with the rear chamber B. 7

As shown in FIGUREZ, the bottom wall 19 of the front chamber A includes a single opening 20 adjacent to the point where the wall section 16 meets the bottom of the body. The opening 20 is of an area substantially smaller than the cross-sectional area of the chamber A taken in a plane normal to the longitudinal axis of the body. This opening is also flush with the bottom wall 19 as shown.

Also included in the interior of the body 10 is a closed tube 21 extending from the rear chamber B through the wall sectoin 16 to the front chamber A. A small weight in the form of a metal ball 22 is disposed within the closed tube 21 and will be actuated by gravity to move between one end of the tube and the other depending upon the attitude of the lure in the water. In FIGURE 2 for example, the ball is shown at the rear end of the tube while in FIGURE 3, the ball is at the front end.

The operation of the fishing lure can best be understood by referring to FIGURES 2 and 3 together. When the lure is first cast into the water, the rear chamber B will fill with water through one or more of the openings 11 as shown in FIGURE 2. Filling of the rear chamber with water causes the rear chamber to assume a lower level than the front chamber A and thus the lure will float with its front end at a higher level than its rear end with respect to a horizontal plane such as that indicated by the dash dot line P. With the rear end lower than the front end, the metal ball 22. will be in the extreme left position as shown in FIGURE 2. The upper air tight Patented July 17, 1962 chamber C will insure that the lure remains in an up-' right position with respect to roll even though the lure may initially be cast into the water in any position. Moreover, because there is only a single opening 29 for the front chamber A substantially no water will enter the chamber A when the lure is in the posit-ion shown since the opening 20 is completely submerged in the Water and thus the water is excluded by the air pressure within the chamber A. This condition will obtain so long as the lure is at rest and inpthe upright position illustrated in FIGURE 2. It is this very important positioning function which is accomplished. by the air tight chamber C.

The equivalent function could be realized, of course, by

weighting the bottom of the lure. The fisherman may pull on the line 13 gently and move the lure about the surface of the water treating the same as a floating object. Stronger pulls on the line 13 resulting in forward motion of the lure will cause a reduced pressure area to develop adjacent the bottom opening 20 by the movement of water in streamlined paths past this opening along the bottom surface. This reduced pressure draws out some of the air in chamber A by the well-known principles of hydro-dynamics and this air is then replaced by water when forward motion of the lure ceases. The front chamber A can thus be gradually filled with water by successive pulls to lower the floating level of the lure and eventually sink the lure. I On the other hand, if it is desired to sink the lure relatively quickly, the fisherman can execute stronger pulls on the fishing line 13. This increased'forward force on the lure when the vane 12 is used will result in pitching until the lure, for example, assumes the position shown in FIGURE 3. In this position, the front chamber A, in addition to shipping'water as a consequence of fluid flow past the opening 2 is' now substantially lower than the rear chamber so'that the opening is at a higher level. As a consequence, finite portions of additional water can enter the single opening 20 as indicated by the arrows 24. Air will simultaneously escape as indicated by the arrows 25. Since however the lure will only attain the maximum pitching amplitude shown in FIGURE 3 for a short time because of relaxation on the line and the buoyancy exhibited by the front chamber A, water 'will'be cut otf from entering the chamber A as the lure rotates back to a position approximately that shown in FIGURE 2. The next successive tug on the fishing line 13 will then result in another pitching forward of the lure as a consequence of the diving vane and result in another finite portion of water entering the chamber A. The ball 22 in tube 21 will augment this pitching action by shift ing the center of gravity of the lure. It will be evident accordingly that by successively tugging on the line 13 a pitching action of sufiiciently large amplitude can be achieved to fill the front chamber A relatively quickly with water.

' Since controlled sinking of the lure can be effected without pitching movements but simply. by elfecting relative action of the water past the single opening 20yas described heretofore, the divin-g'vane and tubeand :ball are not essential features of the invention; However, by employing the vane to cause the desired pitching motion, in combination with the tube and ball, the ball is caused to move back and forth within the closed tube as desired to provide. the desired fish attracting clicking noises as well as augment the pitching action itself.

From the foregoing, it will be evident that the presentinvention provides a greatly improved fishing lure which constitutes a combination of conventional floating type lures and sinking type lure in that the instant lure can be used as a floating lure until the fisherman desires to sink the lure. v

While a preferred embodiment of the invention has been shown and described, various changes and modifications will readily occur to those skilled in the art. The improved fishing lure is therefore not to be thought of as A. limited to the particular structure set forth merely for illustrative purposes.
